V. AIR CALIBRATION (continued)
6.
Push and hold the push button to enter menu mode.
7.
Release the push button while “CAL” is displayed. The display will
alternate between “CAL” and “PUSHnHLD”.
8.
Push and hold the button then release while “Air CAL” is displayed.
9.
The PT5 will perform the calibration. When calibration is complete, the
display will indicate “SAVEd” then turn OFF.
10.
To verify calibration follow steps 1 thru 5 above (taking a
measurement) at 25 ºC, the readings should be 104% ±2%.
NOTE:
The PT5
MUST
be recalibrated any time: the DO sensor is
replaced; the DO membrane or the electrolyte is replaced, or; the Zinc
electrode is cleaned
VI. DO Measurement
CAUTION
: For best results when measuring solution at the extremes of
the specified temperature or DO range
ALWAYS
perform a
TEMPERATURE CONTROLLED, FULL CALIBRATION as described in
the full PT5 Operation Manual. Allow the PT5 to equilibrate by
submerging the sensor in the sample solution for 1 minute prior to taking
a measurement.
•
ALWAYS make sure that the DO Sensor is completely submerged in
the solution being tested.
•
If the expected measurement is < 3 ppm it is particularly important to
perform the ZERO calibration described in the full PT5 Operation
Manual.
1.
Push and release the push button to turn the PT5 ON.
2.
Dip PT5 sensor in solution to be tested and swirl.
3.
Continue to swirl the PT5 in solution while measurement is taking
place.
The following table explains what the LED Indicator light signals indicate
and gives the duration of each signal.
NOTE
: You can turn OFF the unit at any time during live measurement
with a simple press and release of the push button.

MAINTENANCE
I. Routine Maintenance
1.
After each use
ALWAYS
rinse the DO sensor with clean water (preferably DI, RO, or
distilled water), then carefully blot the sensor membrane with a soft, clean, lint-free
cloth to remove any water drops.
2. ALWAYS
replace the hydration cap on the DO sensor after each use.
3.
To replace the membrane cap and/or refill electrolyte solution follow the SENSOR
SETUP instructions.
4.
Do not drop, throw or otherwise strike the PT5. This voids the warranty.
5.
Do not store the PT5 in a location where the ambient temperatures exceed its
specified Operating/Storage Temperature limits.
NOTE:
For instructions on cleaning the DO sensor, performing a sensor check,
troubleshooting, or storing the PT5, download the full PT5 Operation Manual from
www.myronl.com.
II. Battery Replacement
1.
In a
CLEAN DRY
place unscrew the battery cap in a counter-clockwise direction.
2.
Slide the cap and battery housing out of the PT5.
3.
Remove the depleted battery from its housing.
4.
Insert a new battery into the battery housing oriented with the negative end touching the spring.
5.
Align the groove along the battery housing with the guide bump inside the PT5 case and slide the battery housing back in.
6.
Screw the battery cap back on in a clockwise direction. Do not over tighten.
